GCT changed the older "4 star" max. reviews to "5 stars", consistent with new review format, so that overall review average is accurate & useful. We do not know if they changed older 3, 2, 1 or 0 star reviews to fit the new 5 start max. format.
So GCT/OAT can make incremental changes before late Aug to the new review format, if it affects their advertising image or bottom line, e.g. travel invoice & online payment bugs in early July were fixed within days!
We hope that other changes that your customers have requested are coming quickly, e.g. insert date trip started (mo./day/yr.) automatically, same reviewer info as for forum posts, ID/name, trips taken, traveled since date, etc. We just read the last years reviews for Rhine & Mosel, and would have appreciated "date trip started" info., since we leave in late Sept.
